两个通过Jquery从标签中删除星号符号

Question

In a paragraph I have a label that has two asterisk (*) signs. On page Load I want to check if it has two asterisk (**) signs then I want to remove one of them

My HTML looks like:

<p>
    <label for="xyz">**Required</label>
</p>

How is it done via jquery?

Answer 1

Use text() method with callback to iterate and use String#replace method to update the text.

 // get all label which contains 2 adjuscent * $('label:contains("**")').text(function(i, txt) { // iterate over them, replace and update return txt.replace('**', '*'); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <p> <label for="xyz">**Required</label> </p>
